SPECIFICATION forming part of Letters Patent No. 749,109, dated January 5, 1904.

Application filed September 3, 1901. Renewed November 18. 1903. Serial No. 181,737- (No model.)

To all whom it may concern:

Be it known that I, ERASTUS CORNING SOM- ERS, a citizen of the United States, and a resident of Corning, in the county of Steuben and 5 State of New York, have invented a new and Improved Revoluble Window, of which the following is a full, clear, and exact description.

The invention relates to windows having i sashes mounted to slide up and down and adapted tobe turned on pivots for conveniently cleaning both sides of the window.

The object of the invention is to provide a new and improved window which is simple and durable in construction and arranged to permit of conveniently locking the sash to the slide to move the sash up and down or to unlock the sash from the slide for turning the sash on its pivots.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification,in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional front elevation of the improvement, showing one side of the sash locked to the slide. Fig. 2 is a side elevation of the same, showing the sash in section and unlocked from the slide and turned into an angular position. Fig. 3 is a sectional 5 side elevation of the same on the line 3 3 of Fig. 1. Fig. 4 is a side elevation of the mechanism for actuating the locking and unlocking bar, the parts being broken out. Fig. 5 is an enlarged sectional plan view of the improvement on the line 5 5 of Fig. 1. Fig. 6 is a sectional front elevation of the actuating mechanism for the locking and unlocking bar, the section being on the line 6 6 of Fig. 4. Fig. 7 is a similar view of the same on the line 7 7 of Fig. 4. Fig. 8 is a perspective View of one of the pivots for the sash. Fig. 9 is a like view of the removable head for the pivot. Fig. 10 is an enlarged sectional plan view of the improvement on the line 10 10 of Fig. 1,

showing the sash locked to the slide, and Fig. 11 is a like view of the same with the parts in a different position and showing the sash unlocked.

The window has a sash A provided on both sides, at or near the middle thereof, with pivots B, engaging bearings in a slide 0, mounted to slide up and down in the usual guideways D, formed on the sides of the window-frame, as plainly indicated in the drawings. The pivot B is also engaged by the eye of arod E, attached to one end of a counterbalancing chain or cord E, extending over the usual pulley E and carrying at its other endasash-weight. (Notshown.) Each side of the sash A is formed with a recess or groove A, extending nearly the length of the side, and into this recess is adapted to pass a bar F, preferably made of sheet metal and U- shaped in cross-section, as plainly shown in Figs. 5, 10, and 11. The sides of this bar F are formed with a number of angular slots F,engaged by pins F extending transversely and attached to the slide 0, so as to move the bar F. By moving the bar F upward it slides on the pins F and as the slots F are angular it is evident that the said bar F also slides sidewise and moves out of engagement with the recess A on the sash A. (See Fig. 11.) When the bar F is moved downward,it slides sidewise in the opposite direction-- that is, back into the recess A's0 that the sash A is held against turning on its pivot B. When the bar F is, however, in an uppermost position and out of engagement with the recess A, then the sash A is unlocked 83 and can be readily turned on its pivots B for the purpose mentioned. The bar F is mounted to slide in a suitable guideway G, preferably made of sheet metal and secured to the slide 0, as plainly indicated in Figs. 10 and 11. The middle portion of the bar F is formed with apertures F adapted to be engaged by hooks H, carried by the sides of the sash A, so as to hold the bar F against accidental sidewise movement after the bar is moved into position in the recess A. The

bar F is normally held in a lowermost position and in engagement with the recess A by the action of a spring I, held on the guideway G and connected by a hook I with a too pin 1 on the said bar F, as plainly indicated in Figs. 1 and 3.

One of the apertures F is adapted to be engaged bya lug .T on the free end of a spring J, secured to the guideway G, so that when the bar F is moved into an uppermost position and out of engagement with the recess A then the said lug J snaps into the aperture F to hold the bar F telnporarily in an uppermost position-that is, during the time the sash A is turned on its pivots B slightly in eithe rdirection from a perpendicular line of slide C.

In order to move the bar F into most position, the following device is pro-. vided: Near the lower end of the bar F is arranged a link K, pivoted at K to the bar and formed at its free end with an arm K (see Figs. 4, 6, and 7,) extending through an opening F in one side of the bar F to a casing L, held on the slide 0. This arm K is adapted to be engaged by the angular portion N of a lever N, fulcrumed at N in the casing L and extending to the outside of the slide C, so as to be within convenient reach of the operator. vVhen the lever N is swung upward, its angular portion N imparts an upward movement to the arm K so that the link K imparts an upward sliding motion to the bar F to move the same out of engagement an upperwvith the side of the sash A. When the bar F moves upward, it places the spring I under tension, and at the same time the lug J of the spring J engages one of the apertures F to hold the bar in an uppermost position. The lever N falls of its own gravity or the operator places it in lower positions immediately after raising it sufficient to allow lug J to engage the aperture F in bar F, which holds it until sash A is turned on its pivot B out of line with slide 0; but the bar Fstill holds its upperposition, being in contact with the sides of sash A until sash A is fully revolved or moved back to its perpendicular position in line with slide 0, when the spring I pulls the bar F downward into the recess or groove in sash A, the apertures F in bar F engaging the hooks in the recess or grooves on the sides of sash A, thus automatically locking sash A to slide 0.

The pivot B, above referred, to is preferably secured on a plate B, screwed or otherwise fastened to the sash A, and on the free end of the pivot B are formed lugs B engaging corresponding recesses in a head 13, formed with a central aperture for the passage of a screw B screwing into the pivot B to hold the head B in place, and by adjusting the screw B with the pivot B the plate or head B presses the slide against the sash A to form a proper friction that will hold the sash A in any desired position after being turned upon the pivots B. (See Fig. 5.)

It is understood that when the sash A is locked by the bar F to the slide 0 the sash moves freely up and down with the slide to open and close the window, as desired, and when the sash is unlocked from the slide 0, with the bar F then standing in an uppermost position, the sash A can be turned on its Meade pivots B to permit of conveniently cleaning both sides of the window from the inside of a room.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A window havingslides on which the sash is mounted to turn, and locking devices for locking the sash to said slides to move up and down with the latter, or to disengage the sash from the slide to allow the sash to turn on its -pivots; each of the locking devicescom prising a spring-pressed bar slidable up and down and sidewise on the said slide to move it out of and into a recess or groove in the said sash, and adapted to be automatically moved into the recess or groove of the sash when the sash is moved into a vertical position, as set forth.
